Suprisingly not that bad. The edge is better than most made it out to be, as far as I'm concerned. It's obviously not as fast as broadband, but it's doable for just getting to pages. Myspace will load and it takes around 2 minutes to load up and log in and crap. Normally i'd be like 15 seconds on my home computer. Yet to use it with wifi.
Haven't tried a monster load like myspace not that I would try to navigate Myspace on this phone anyway. Wifi at my house was really good and fast, automatically picked up the signal typed in my password and I was on.
